People have asked before, what is the white thing in the middle of each pit?

The 4000-pixel version gives a better view of those white things than I can recall having seen before.

Top notch ! Both lightning and detail/shapness.
Those small pits looks interesting.

Thanks Rik, microman !
Wikipedia says:
"Similarity in appearance to native species
Easily confused with Brochymena and Euschistus, the best identification for adults is the white band on the antennae. It is similar in appearance to other native species of shield bug including Acrosternum, Euschistus, and Podisus, except that several of the abdominal segments protrude from beneath the wings and are alternatively banded with black and white (visible along the edge of the bug even when wings are folded) and a white stripe or band on the next to last (4th) antennal segment.[32] The adult rice stink bug (Oebalus pugnax) is distinguishable from the brown marmorated stink bug by noting the straw color, the smaller size, and the elongated shape of the rice stink bug.[33]"

My specimen does not have banded antennae but has banded abdominal segments . "Face" top edge is even - looks like not a marmorated. One more thing helps to identify - shape of the "shoulders" but I do not remember the details... So, I'm not sure ....

White things - most probably they are olfactory smell receptors. They look very impressive at the big magnification. More pictures to follow ..._________________Saul

Excellent stereo. Once again I am (pleasantly!) surprised to suddenly see such clear 3D structure. I keep expecting the surprise to stop happening, but that's probably unrealistic given that I've been noticing it for well over 30 years now.

Thanks, Rik!
It is very good feeling , something similar what I had long time ago - after developing negative film and removing it from the tank, you never know what you'll see ... same with stacking ...
Thank you again for your great software !_________________Saul

Excellent pictures, and interesting.
On the bottom of all the dark brown depression sits a little cup with white or transparent rim. In the middle of this cup is a littel club. Anybody knows what this is?
Could it be kind of sensoric apparatus, detecting prssure/contact. Perhaps heat or chemical sensors? Or is it just how you look good in this family?_________________Troels Holm, biologist (retired), environmentalist, amateur photographer.
